COLTER-BAN D.

SPECIFICATION forming part of Letters Patent No. 403,399, dated May 14, 1889. Application filed January 19, 1889. Serial No. 296,844. (No model.)

To all whom it may concern:

Be it known that I, ALONZO JOHNSON TA- TUM, a citizen of the Unit-ed States, and a resident of Finch, in the county of Greene and State of Arkansas, have invented certain new and useful Improvements in Colter-Bands; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of my im- 1 5. proved colter-band, showing the same applied to the beam of the plow. Fig. 2 is a cross sectional view. Fig. 3 is a longitudinal sectional View, and Fig. 4 is a detail view in perspective of the band.

Like letters of reference denote corresponding parts in all the figures.

My invention relates to colter-bands for securing the colters or cutters in proper position upon the plow; and it consists, more particu- 2 5 larly, in providing a construction whereby I am enabled to adjust the colters so as to bring them close to or away from the point of the plow, at the same time retaining them in a secure and firm manner; and to this end it consists in the'improved construction and combination of parts of the same, as hereinafter more fully set forth and described.

In the accompanying drawings, the letter A represents the beam of the plow, provided with a series of longitudinal slots, B, and 0 represents the colter-band, through which said beam is passed. This colter-band is provided with similar longitudinal slots, D, upon the upper and under sides thereof, and is also 40 provided on its upper and under sides with lugs E E E E, said lugs being provided with screw-threaded holes F F F F for the recep tion of set-screws G G G Gr. The upper por= tion or top of the band is also provided with laterally-extending flanges H H, provided with holes I I for the reception of bolts J J, said holes and bolts, if desired, being screwthreaded. The sides of the band are likewise provided with screwthreaded holes K K,

through which pass set screws L L, and when the colter is placed in the central slot said set-screws also pass through the inner Walls of the slots and bear against the colter.

In operation the beam of the plow is inserted through the band until the longitudinal slots therein register with the slots in said band, and the band is then secured to the beam by means of the bolts J J, passing through the laterally-extending flanges H H into the beam. The colter or cutter is then passed through either of the longitudinal slots and secured therein by means of the set-screws passing through the lugs upon the upper and under portions of the band. The knife or colter may still further be secured by means of the set-screws passing through the sides and bearing against the same. By this construction the colter is made to make the incision in the soil in advance of the share; and as it has heretofore been found difficult to provide an effective means for securing the colt-er to the beam of the plow I have provided the construction of lugs through which the set-screws pass, and by which I am enabled to overcome these difficulties, as it will be observed that the colter can be secured in a most effective and firm manner by means of these set-screws, and at the same time the colter may be adjusted at different angles within the slots, either close to or away from the point of the plow, as may be found most desirable, and also adjusted vertically to make either a shallow or deep incision. Further, the colter may be adjusted laterally by transferring it from one of the series of longitudinal slots to the other, so that the knife may be shifted in order to make the incision at different points. It is also obvious that, if desired, three colters may be used, or, in fact, any number employed, by simply increasing the numo ber of slots in the band and plow-beam.

My device is, furthermore, simple of construction and can be readily and quickly adjusted with but very little difficulty.

Having thus described my invention, I 5 claim and desire to secure by Letters Patent of the United States- 1. As an improved article of manufacture,

a colter band having the upper portion thereof provided with laterallyextending 10o or cutter, and the set-screws, substantially as set forth.

3. The combination, with the beam of a plow provided with a series of longitudinal slots, of the colter-band having the upper portion thereof provided with laterally-extending perforated flanges, and also having its upper and under portions each provided with longitudinal slots and vertically-extending perforated lugs, the colter or cutter, and the set-screws and bolts, substantially as set forth.

4. The combination, with the beam of a plow provided with a series of longitudinal slots, of the colter-band having the upper portion thereof provided with laterally-extending perforated flanges, its upper and under portions each provided with longitudinal slots and vertically-extending lugs, said lugs having screw-threaded holes, and having its sides provided with screw-threaded holes, the colter or cutter, and the set-screws and bolts, substantially as setforth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
